Android Facebook身份驗證失敗

Question

我正在嘗試將facebook登錄集成到我的應用中。我在facebook開發人員網站上閱讀了文檔，但它不適用於我。這裏是我的源代碼：

    super.onCreate(savedInstanceState);

} 

private void findViews() { 
    btnFblogin = (Button) findViewById(R.id.btn_login_facebook); 
    btnGoogleLogin = (Button) findViewById(R.id.btn_login_google); 

    btnFblogin.setOnClickListener(this); 
    btnFblogin.setOnClickListener(this); 
} 


@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.login, menu); 
    return true; 
}

    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long

    int id = item.getItemId(); 
    if (id == R.id.action_settings) { 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
}

    } 
}

} 

private void startFacebookSession() { 
    Session session = Session.getActiveSession(); 
    if (session != null && !session.isOpened() && !session.isClosed()) { 
     openSession(session); 
    } else { 
     Session.openActiveSession(this, true, statusCallback); 
    } 
} 

private void openSession(Session session) { 
    Session.OpenRequest openRequest = new Session.OpenRequest(this); 
    openRequest.setPermissions(Constants.FACEBOOK_PERMISSIONS); 
    session.openForRead(openRequest); 
}

     if (session != null && session.isOpened() && !TextUtils.isEmpty(session.getAccessToken())) { 
      Request.executeMeRequestAsync(session, new Request.GraphUserCallback() { 

       // callback after Graph API response with user object 
       @Override 
       public void onCompleted(GraphUser user, Response response) { 
        if (user != null) { 
         Intent intent = new Intent(getApplicationContext(),HomeActivity.class); 
         startActivity(intent); 
         Toast.makeText(getApplicationContext(),"Hello" + user.getUsername(),Toast.LENGTH_SHORT).show(); 
        } else { 
         Toast.makeText(getApplicationContext(),"Login failed",Toast.LENGTH_SHORT).show(); 
        } 
       } 
      }); 
     } 
    } 
} 

} 

吐司總是顯示「登錄失敗」。任何人都可以幫我解決這個問題？

Answer 2

我真的建議你使用SimpleFacebook庫。我開始使用Facebook SDK，但我意識到它有一個糟糕/複雜的軟件設計。

如果你想正確使用它，你必須先花時間學習奇怪的概念。

SimpleFacebook這是Facebook應該做的。

只是爲了得到一個想法，有關如何執行任務登錄一個例子：

//初始化回調監聽：

OnLoginListener onLoginListener = new OnLoginListener() { 
    @Override 
    public void onLogin() { 
     // change the state of the button or do whatever you want 
     Log.i(TAG, "Logged in"); 
    } 

    @Override 
    public void onNotAcceptingPermissions(Permission.Type type) { 
     // user didn't accept READ or WRITE permission 
     Log.w(TAG, String.format("You didn't accept %s permissions", type.name())); 
    } 

    /* 
    * You can override other methods here: 
    * onThinking(), onFail(String reason), onException(Throwable throwable) 
    */ 
}; 

mSimpleFacebook.login(onLoginListener);
